masses.

To all whom-it may concern.

Be it known that I PHILIPP LIYA a citizen of the United States, andresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and i useful. improvements in ire-Bending Machines,of which the following isa specification.

This invention relates to improvement in wire bending and cuttingmachine.

An object of this invention is toprovide an effective, efficient andinexpensive device for bending and cutting wire to a shape and size tobe used as so-called hair pins for interior decorating work or inconjunction with construction workin general.

Other objects of this invention are to pro.- vide in such a device ameans to receive the wire to be bent, adjustable means. for limit ingthe length of such wire and means for cutting same after part of thebending process has been gone through.

Further objects of this invention are to provide in such a device alever pivotedly connected to a platform and adapted to move in ahorizontal planeysaid lever being provided with a female bending die anadj ust able male bending die, the male and female dies being sodisposed relative to each other that when said lever is swung to aposition at right angles to its original inoperative position, the wireis curved so as to form two equal and parallel legs when cut,: and meansfor limiting the travel of said lever.

Still further objects of this invention are I to provide another levermounted on said platform adapted to swing in a vertical planeandprovided with" a bending member so disposed as to bend a portion of thenow formed parallel legs of the wire, downwardly,- and means forlimiting its *downward travel. 1

A still further object of this invention i to provide a device which bymaking suitable and convenient changes may be used for similar purposes.

The above and further objects in view will more fully be understood fromthe following description together with the accompanying drawingsforming part of this specification and in which, I V

Figure -lis a perspective view of the bending lever showing the femaledie upon the under-surface thereof.

Figure 5 is a perspective view of a preferred form of an adjustable malethe.

Figure 6 is a perspective view of a preferred form of an adjustable stopmember. .Figure 7 shows a product of my device.

The drawings disclose a preferred embodi ment of my invention having aplatform or base 1 made from suitable material;

Base 1 has formed thereon. and made integral therewith. the transverseparallel wall-like projections or uprights 2 and 3, and the longitudinalwall-like projection or upright l, the latter joining with the rear endsof the former. i i

Base 1 is provided with an opening 4 between uprights 2 and 3. UprightsE2 and 3 are bored to receive a bolt 5 upon which is mounted a lever 6.This lever is adapted to travel in a vertical plane and has formedthereon a protrusion 7 for limiting its downward position.

Secured to the sides of lever 6 by suitable means are bender 8 andknife'or cutter 9, the former being connected to the inner side and thelatter to the outer side thereof extending slightlylower than theformer.

Secured to the lower end of upright 2 in a slot is a cutting plate 10made from suitable material. and directly above this plate there isformed an aperture 11 through which a wire may be drawn to be bent andcut. A bender plate 11 is inserted and secured in a slot provided inbase 1- directly abreast of bender 8 when the latter is in downwardposition. Lever 6 is disposed between uprights 2 and 3 so that thereexists between bender 8 and bender plate 11' sufiicient space in ordertogive play to the bending wire and so that knife or cutter 9 contactswith cutting plate 10 when lever 6 is in extreme downward position. aswill more fully be explained below.

Pivoteclly connected to base 1 by suitable means 12 is a lever orbending member 13, adapted to travel in a horizontal plane, beingprovided at its under-surfacewith an arcuated female bending die ldis'posed at about its center, and a boss 15. said'lever being providedwith a suitable handle 15.

yAn adjustable male bending or forming die 16, slotted at 17 to receivean adjusting bolt 18 for securing it in grooved portion 19 of base 1, isprovided with a curvedportion 20 for bending a wire as will be explainedbelow. Lever 13 is cut out at 21 to clear bolt 18. I

Lever 13 is prevented from going too far back by upright 4. When movedin the direction of the operator it is held fixed in extreme position byclamping member 21' secured to base 1. This clamping member is disposedat a suitable distance from the pivoted point of lever 13 andon a lineat right angles to the inoperative position of the latter, so that whenlever 13 is in clamping position, it is at right angles to itsinoperative position, the engaging portion of die 14 being injuxtaposition to adjustable die 16. I

. An adjustable wire stop 22 having an upright portion 23 is slotted at24 to receive an adjusting bolt 25 for securing it in grooved portion26of base 1.

The wire is bent to the desired shape as follows: Adjustable stop 22 isadjusted and clamped in position by bolt 25, until the distance betweenupright portion 23 and cutting plate 10' is equal tothe desired lengthof wire to be bent; ire 27, which is usually coiled on a spool, is drawnthrough aperture 11 to the inner end of adjustable stop 22, the wirepassing alongside adjustable male die 16, as clearly shown in .F 'igures1 and 2. Lever 13 carrying fe male die "14 is then movedtowards the wireand during the course of its motion carries the wire with it, the latterengaging male die '16. During this operation female die 14 cooperateswith male die 16 in such manner that the wire is bent around curvedportion 20 of the latter in a hook shape and forms a leg 28 parallel tothe first portion 29 of thewire when lever 13 reaches clamp 21'. Theposition now occupied by lever 13 and female die 14 is shown by dotted"lines in Figure By means of clamp 21, lever 13 is held in fix-eddownward position so that the'curved portion of the wire is heldimmovable thereunder during the following operations.

Lever-6 is now drawn downward and due to knife or cutter 9 beingslightly lower than bender 8", the wire is first cut so that two equalparallel legs 28 and 30 of the hook shape are produced and then as lever6is movedfurther-downward until protrusion 7 engages base 1, theparallel legs of the hook are bent downwardly by bender 8.

iBy wayof these operations, so-called hair pins, as shown in Figure 7,are produced.

extract thesenow formed hair pins,

lever '6 is" raisedli and the pin released by swinging ilever 13 to'backward position as shown miull lines, Figure 1. i .1; Incon unctionwith imy device, a spring means not shown, may be attached below thecurved portion of the hair pin for lifting the latter over male die 16and causing it to fall through ,opening a into a container convenientlyplaced thereunder.

These hair pins may be made of any desired length, within limitationsotthe size of the machine which may of course be varied by adjustingstop 22. It is to be observed that male die 16 shouldbe adjustedcorrespondingly, so that a line drawn tangentially from the highestpoint of curved portion 20 divides the portion of the wire to be bentequally. I

The hair pins so formed may be used for interior decorating work. and inconjunction with construction work in general. l/Vire netting, expandedmetal or the like may be attached which is subsequently covered withvplaster or similar building material. e I

My device is not limited to producing the particular shape of pinsdescribed above, for by changing the dies and other bending parts it maybe adaptedfor any similar pur- JO'SG.
